DISH-WASHER.

Specification of Letters Patenti Patented April 28, 1907.

Application filed April 16,1906. sai-in No. 312,047.

To all whom it vnay concern.-

citizen of the United States, and a resident of St. Louis, Missouri, have invented certain new and useful Improvements in Dish-Washers, of which the following is a s ecification containing a full, clear, and exact escription, reference being had to the accompanying drawings, forming a part hereof;

My invention relates to a dish washer,- and the. object of my inventionis to construct a simple, inexpensive, and practically automatic apparatus for quickly and thoroughly washing dishes and culinary utensils.

A further object of iny invention is to construct a sim le ap aratus which is adapted for use in t e or inary kitchen sink, and which utilizes hot water from the hot water tank in the kitchen.

A further object of my invention is to provide a dish washer with means whereby the dishes and utensils may be quickly placed within or removed from the housing of the apparatus. a

To the above purposes, my invention consists of certain novel features of construction and arrangement of parts, which will be hereinafter more fully set 'forth, pointed out in my claims, and illustrated in the accompanyingrdrawings, in which igure 1 is a perspective view of a dish washero'f my improved construction; Fig. 2 is a vertical section taken on the line 2-2 of Fig. 1; Fig. 3 is a transverse section taken on the line 33 of Fig. 2; Fig. 4. is a rear elevation of the dish washer; Fi 5 is a vertical section taken longitudina 1y through the center of a modified form of the dish washer; Fig. 6 is a rear elevation of this modification; Fig. 7 is a plan view of a pan made use of when this form of the washer is emlplloyed.

the construction of my improved dish washer, I make use of an outer cylinder 1,

- which is slightly sma the forward end of which is normally closed by a removable cover 2. The cylinder is horizontally disposed, and is supported by suitable legs 3. Arranged on the interior of the cylinder 1 is a erforated cylinder 4,

ll er in diameter than is said cylinder 1 in order to form a narrow annular chamber 5 between said cylinders 1 and 4. The rear end of the outer cylinder 1 is closed, and the inner cylinder is open at each end and abuts a ainst the ends of the outer cylinder. Leading through the top of cutoff va ve 7. Located in the pipe 6, a short distance from the valve 7 is a cup 8, prov ded with a suitable cut-off valve 9, and

which is adapted to receive a suitable liquid soa or cleansing compound. A hose 10,

lea ing from a suitable source of hot water sup 1y is detachably seated on the outer end of t e pipe 6. Connected by meansrof a T union 11 to the pipe 6 is a pipe 12, which'extends downwardly against the rear end of the cylinder 1, andsaid pipe 12 is extended horizontally, as indicated by 13, through the center of a slot 14, which is formed in the rear wall of the cylinder, and said portion 13 of the pipeextends forwardly on the interior of the perforated cylinder 4. A lurality of short erforated nozzles 15 extend upwardly from t 's portion 13 of the pipe 12 on the in terior of the'perforated cylinder 4. Suitably located in the ipe 12 is a cutoff valve 16.

A pair of ra' s 17 connected to and supporting a suitable rack 18 are arranged to slide longitudinally within the erforated cylinder 4, and said rack 18 is a a ted to receive the dishes and utensils WhlCh are to be washed. I k In the operation of my improved washer, the rack 18 is withdrawn from the perforated cylinder 4, and after the dishes are loaded into l said rack, the same is positioned on the ihterior of the perforated cylinder 4, after whlch a the cover 2 is placed in position to close the.

forward end of the washer, the valve 9 is now opened to allow the proper amountof lilfiiiid soa to dischar e into thepipe 6, after W ch sai valve 9 is c osed, and as the valve 7 is o ened, .the hot water'will discharge throug the pipe 6 carrying the liquidsoa therewith, and said hot water and soap wi discharge into the cylinder 1. As the annular chamber between the two cylinders 'fills with hot water, the same will discharge through the minute apertures in the perforated cylinder 4, and will thus form a series of small jets which are directed against the dishes and utensils carried by the rack 18. The water discharging from the interior of the cylinder 4 passes out through the slot 14 in the rear wall of the cylinder 1.

This action very quickly and thoroughly' washes the dishes, and when the same are thoroughly cleansed, hot water is allowedto discharge onto the dishes fora short space of time to rinse and heat the same, thus mate- IIO ' they have been remove When desired, the which results in dishes.

' water is limited; and to operate the washer, a

Y positioned within the inner cylinder, and the pots or a verticallyar'ranged pipe22, the lower end enters the compartment 20, and the lower manually operated, and the water is drawn v6, or throug the pipes 12 and 13. the same supply of soapsuds or clear water i said dishes after from the washer. valves 16 may be opened, a discharge of the water from the perforated nozzles 15, which. are arranged below; the rack carrylng the rially assisting iil dryintg' Where it is desired to Wash pots, kettles, and similar dispensed with, and a rectangular frame 26 which is covered with suitable wire screen is kettles are inverted upon this frame immediately over the nozzles 15.

In the modification seen in Figs. 5, 6, and '7, I 'make use of a pan 19,'having a compartment 20 for clear water, and a compartment 21. for soapsuds. The pipe 6 is connected to of which is connected by a two-way valve 23 to branches 24 which extend downwardly, and the lower 'end of one of said branches end of the opposite branch enters the compartment 21. Located in the pipe 22 is a small rotary pump 25, of any suitable construction, and which is adapted to draw water up throu h the branches 24, and force the same up tILrough the pipe 6 into the annular chamber between. the cylinders 1 and 4. The water from. this form of the washer dischar es through an opening 27 in the front end 0% the cylinder 1, and arranged in the front end of the an 19 is a screen section 28, through which the water passes in discharging from the aperture 27 into the compartment 21. This form of the washer is adapted for use where the supply of hot supply of clearhot water is located in the com artment 20, and a supply of soapsuds in t e compartment 21. The dishes or utensils to be washed are now located on the rack 8 or frame 26, and, after the two-way valve has been properly set, the pump 25 is up from the plan and forced through the ipe T us,

heavy utensils, the rack 18 1s can be used continuously washing or rinsing the dishes.

A dish washer improved coristrucand durable, can be and the dishes are quickly tion is simple, strong, quickly loaded or unloaded, placed in the perforated cylinder and thoroughly cleansed.

I claim:

1. In a dish washer of the class described, an outer cylinder, an innerperforated cylinder, means whereby dishes are held within the perforated cylinder, means whereby water under. pressure is delivered to the annular chamber between the cylinders, and means whereby cleansing compound is discharged into the water in advance of its, discharge into the annular chamber; substantially as specified.

2. In a dish washer'of the class described,

der, there being an annular chamber formed between said cylinders, which chamber is closed at the ends of the cylinders, a removable cover closing one end of the outer cylinwithin der, a dish rack removably positioned the perforated cylinder, a pipe leadin to the annular chamber, and a branch pipe eading through the rear end of the outer cylinder to the interior of the inner cylinder; substantially as specified.

3. In a dish washer of: the class described, an outer cylinder, an inner perforated cylinder,- means whereby dishes are held within s an outer cylinder, an inner perforated cylin- 7O the perforated cylinder, means whereby 1 water under pressure is delivered to the annular chamber between the cylinders, means whereby cleansing compound is discharged into the water in advance of its discharge into the annular chamber, and means whereby the discharge of water and cleansing compound to the cylinder is controlled; substantially as specified.'

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.
